Survival and bioaccumulation data for sensitive salmonids exposed to 6PPDQ with additional survival data for two bass species Survival and bioaccumulation data for sensitive salmonids exposed to 6PPDQ with additional survival data for two bass species
This data set includes survival data for five fish species [Coho Salmon (Oncorhynchus kisutch); Brook Trout (Salvelinus fontinalis); Rainbow Trout (Oncorhynchus mykiss); Smallmouth Bass (Micropterus dolomieu); Largemouth Bass (Micropterus nigricans)] exposed to various concentrations of 6PPD-quinone (6PPDQ) for up to 96 hours and then held in clean water for one week post exposure...
Effects of dietary organic selenium on growth, survival, and reproduction in Hyalella azteca and Chironomus dilutus Effects of dietary organic selenium on growth, survival, and reproduction in Hyalella azteca and Chironomus dilutus
Chronic selenium toxicity thresholds are based primarily on dietary organoselenium exposure and subsequent reproductive effects in fish. Available chronic selenium toxicity data suggests that invertebrates are less sensitive than fish, but chronic invertebrate studies are limited. We evaluated yeast-based diets for chronic toxicity studies with Hyalella azteca and Chironomus dilutus...
Preliminary data on survival of Neocloeon triangulifer in sodium chloride bioassays fed differently aged diatoms Preliminary data on survival of Neocloeon triangulifer in sodium chloride bioassays fed differently aged diatoms
This data set includes mortality data from acute toxicity tests with aquatic larvae of the mayfly, Neocloeon triangulifer, exposed to sodium chloride. Two separate tests were conducted and fed diatom diets that were either 7-days-old or 13-days-old.
Survival of juvenile mussels (Lampsilis siliquoidea) exposed to 6PPD and transformation products Survival of juvenile mussels (Lampsilis siliquoidea) exposed to 6PPD and transformation products
This data set includes mortality data from acute toxicity tests with juveniles of the mussel, Lampsilis siliquoidea exposed to 6PPD and 6PPDQ. Concurrently collected analytical chemistry and general water quality measurements are included.
Concentration of PFOS (perfluorooctanesulfonic acid) in water and freshwater diatoms (Mayamaea atomus) in a bioaccumulation study conducted at U.S. Geological Survey, Columbia Environmental Research Center in July 2021 Concentration of PFOS (perfluorooctanesulfonic acid) in water and freshwater diatoms (Mayamaea atomus) in a bioaccumulation study conducted at U.S. Geological Survey, Columbia Environmental Research Center in July 2021
Two laboratory experiments were conducted to understand PFOS (perfluorooctanesulfonic acid) bioaccumulation in freshwater benthic diatoms (Mayamaea atomus). The first experiment tested bioconcentration at multiple PFOS concentrations (0, 0.01, 0.1, 1, 10, 100 micrograms per liter) after 7 days of exposure. The second explored uptake and depuration of 0.1 micrograms per liter PFOS at...
Stormwater concentrations of tire wear particle leachate compounds and survival of early instar mayflies (Neocloeon triangulifer) exposed to 6PPD and transformation products Stormwater concentrations of tire wear particle leachate compounds and survival of early instar mayflies (Neocloeon triangulifer) exposed to 6PPD and transformation products
This data set includes concentrations of selected transformation products (TPs) of the tire antioxidant, 6PPD, including 6PPD-quinone (6PPDQ) and 4-hydroxydiphenylamine (4-HDPA) in water samples collected during a rain event from two urban rivers in the Greater Toronto Area, Ontario, Canada. In addition, mortality data from acute toxicity tests with aquatic larvae of the mayfly...

Effects of dietary selenium on the amphipod Hyalella azteca and the midge Chironomus dilutus Effects of dietary selenium on the amphipod Hyalella azteca and the midge Chironomus dilutus
Chronic selenium (Se) water quality criteria are based primarily on dietary organoselenium exposure and subsequent reproductive effects in fish. Available chronic Se toxicity data suggests that invertebrates are less sensitive than fish, but chronic invertebrate studies are limited.

Sensitivity of mayfly Neocloeon triangulifer to a reference toxicant is significantly impacted by the age of the diatom feed species Navicula pelliculosa Sensitivity of mayfly Neocloeon triangulifer to a reference toxicant is significantly impacted by the age of the diatom feed species Navicula pelliculosa
The development of standardized toxicity tests is critical for assessing pollutants in aquatic ecosystems. The mayfly Neocloeon triangulifer offers advantages as a test species due to its asexual reproduction, short life cycle, and high sensitivity to pollutants. However, we identified variability in response sensitivity to pollutants, which may stem from the nutritional composition and...

Concentration dependency of PFOS bioaccumulation by freshwater benthic algae Concentration dependency of PFOS bioaccumulation by freshwater benthic algae
Although perfluorooctanesulfonic acid (PFOS) has been voluntarily phased out, it remains the most abundant and frequently detected PFAS compound in biota worldwide. A deeper understanding of how PFOS enters the aquatic food web at the energetic base is needed to better characterize and predict the general patterns of PFAS trophic transfer. Research on bioaccumulation by primary producers...

Selenium differentially influences methylmercury retention across mayfly life stages Selenium differentially influences methylmercury retention across mayfly life stages
Though high mercury and selenium concentrations are individually toxic to organisms, there is a hypothesized antagonistic relationship. This potential mercury–selenium interaction is under-studied in aquatic macroinvertebrates, particularly in relation to complex life histories. We examined the proposed effect of selenium on methylmercury accumulation between four life stages for a...

Acute Toxicity of 4-hydroxydiphenylamine (4-HDPA) and N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine-quinone (6PPDQ), transformation products of 6PPD, to early instars of the mayfly, Neocloeon triangulifer Acute Toxicity of 4-hydroxydiphenylamine (4-HDPA) and N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine-quinone (6PPDQ), transformation products of 6PPD, to early instars of the mayfly, Neocloeon triangulifer
Our analysis of water samples collected during a rain event from two urban rivers in the Greater Toronto area, Ontario, Canada, indicated that selected transformation products (TPs) of the tire antioxidant, N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD), including 6PPD-quinone (6PPDQ) and 4-hydroxydiphenylamine (4-HDPA), were present at concentrations >1 µg/L. In acute (96-hr)...

Evaluation of chronic effects of potassium chloride and nickel on survival, growth, and reproduction of a unionid mussel (Lampsilis siliquoidea) Evaluation of chronic effects of potassium chloride and nickel on survival, growth, and reproduction of a unionid mussel (Lampsilis siliquoidea)
The ASTM International standard test method for freshwater mussels (E2455‐13) recommends 4‐week toxicity testing with juveniles to evaluate chronic effects on survival and growth. However, concerns remain that the method may not adequately address the sensitivity of mussels to longer term exposures (>4 weeks), particularly in relation to potential reproductive impairments. No standard...
